Causes of rosacea

The cause is not very clear. It may be caused by sebum overflow, due to various harmful factors inside and outside the body, causing dysfunction of the vasomotor contraction and nerve dysfunction in the affected area and long-term expansion of capillaries. Folliculosis and local repeated infections are important factors. Alcoholism, smoking, irritating diet, dysfunction of digestive tract, endocrine dysfunction (especially menopause), mental factors, focal infections, hot and cold factors that act on the skin for a long time, such as high temperature work, sun exposure, cold, wind, etc. Can induce and exacerbate the disease.

When the damage is deeper and larger, cysts, cysts, and deep inflammatory nodules are formed. The mouth of the hair follicles on the nose and cheeks is enlarged, which can rise and fall within a few years, sometimes light and heavy.
